When I use for example the terrain raise and lower tool and after that try to change to something like the smoothing tool or the paint thing, it wont let me use the new tool. Instead it continues to raise or lower the terrain. Same occurs with the slider settings of the different tools.
I guess this must be some kind of a bug. So if anyone has ever come across with something similar please let me know if you came up with a fix for it.
ps: The terrain tool changes seem to update after a while but there is still a significant delay.
